Well I tested the GOSM Big Block Sunday. Did four 5lb. chickens 2 with a rub and 2 beer can.. Must say they were great, and the smoker is AWESOME.. Once I got the temp where I wanted, it never moved until I opened the door. Its everything that I had been told... Easy clean up, and I had all kinds of space left with the 4 chickens in there... Next up 2 briskets.. I highly recommend the Big Block!!
